What CMO right now is how many places in Norway don't accept credit cards. Most restaurants do (although AmEx not so much) and most bigger shops do accept them though. However, machines such as parking meters, vending machines, seemingly don't accept any CCs. Luckily I did bring my Wise debit card. Also, service providers such as phone companies reject payments with international billing addresses. It made getting a local number a bit tricky.
There's a culture here around credit cards where you're considered, by many, to be irresponsible by "using money you don't have". There's a popular TV show called "Luksus fellen" which translates to "luxury trap" meaning people who abuse credit cards and live beyond their means to a point where they're trapped, and some have to file for bankruptcy. They don't have rewards cards here, so most people just use debit cards. I've noticed some looks when a card is declined because they don't accept credit cards. Very odd.
Norway is so progressive in many ways, but a bit old fashioned/conservative/quaint in others
